Application filed August 27, 1907. Serial No. 390,309.

To all whom it may concern:

Be it known that I, Hnunr S.- GASKILL, a citizen of the United States, residin at Lansing, in the county of Ingham and tate of lvlichigan, have invented a new and useful Improvement in Flushing-Valves, of which the following is a specification.

My invention relates to direct pressure flushing, valves and its object is to make a valve which will entirely dispense with the necessity of a tank and in which the amount and dnration'of the discharge will be readily controlled and the device be reliable and ellicient in operation. I attain'these purposes by the means set forth in the'aecoinpanying drawings in which Figure l is a vertical section at right angles to the operating shaft. Fig. 2 is a vertical section throu h the center of operutingslmft. Fig. 3 1s a detail 01" one form ol' the adjusting mechanism for regulating the rate of closing ol. the-flushing valve.

Similar numbers. refer to similar parts in the dili'erentdrawings.

In the drawings, 1 is the water pipe, the opening in which is closed by the valve 2 which may be of aluy ordinary preferred in the drawings, what is known as the Fuller cock is employed. The stem 3 of this valve is connected to a pin in a shaft 4 so that the .valve will be closed and opened by the revolution'lof the shaft 4. Attached to the side of the pipe 1 is a dash pot 5 communicating with the pipe 1 below the valve 2 by an opening 18, for the admission of water from the pipe 3 into the dash pot A piston 10, 0 erated by a rack 9 and sci-tor 7, the latter being mounted on the shaft 6 which .controls' the motions of lhe valve 2, closely fits the interior of the dash pot. in this piston is an opening closed by a valve 'l-l: which' is l\'cpt closed by a springl3 or other suitable means. A tube [7 conncrls the upper and lower parts of the dash pot 5, permitting the water lo'pass from one side to the other of the piston '10 when lhn valve l l isrloscd. It is evident that instead of a tube [7 a. hole 20 may he formed in llapiston 10, or the piston ilscll' may lie-made to [it the interior ol? the dash pot with sullirient looseuess to permit the water to pass it, but I do not. (.Ollhltlfll, this last l'orm so desirable as it does not admit ol. the exactnes of regulation of lhe other coustrmztions. A regulating screw 'l.) is inserted in the tube l7 or in the opening 20 if. that is employed for the purpose of controlling the size 0t the openin and consequently, the rate of 'descent o the piston 10. \Vhile the weight of the handle 16 and lever 11 combined with the pressure of the water on the valve 2 are ordinarily sufficient to force down the piston 10 and close the valveil, a spring 8 of any desired construction, in this case a. spiral spring, may be employed to assist in pro ducing this effect.

The operation of the device is as follows: Supposing the parts to be in the position shown in Fig. 1. As the handle 16 is raised from position 21 to. position 22, a vacuum will be formed below the piston 10 which will open the valve 14, thus filling the chamher below the piston 10 with Water. At'the same time the revolution of the shaft 6 will open the valve 2 permitting the water to escape through the pipe 3. As soon .as the handle 16 is released, however, its .weight with the weight of the handle bar 11, and the pressure of the water on the valve 2, assisted by the spring 8 if that is employed, will tend to revolve the shaft 6 and thus close the valve 2. This action will be resisled by the water below the iston 10 which can only descend as rapid y as the water can escape through the opening 20 or the pipe 17,- which may be adjusted to any desired rapidity by the screw 19, thus placing the quantity of water discharged under the fullest degree of control. A cap 23 closes the upper end of the dash pot so as to prevent the escape of water by overflow,

but the opening 18 being below the valve 2,

the water in the dash pot 5 will not be under pressure and so will have little tendency to escape. The shaft 6 passes through a stuffing box 12 to prevent leakage at that point.

I claim as my invention and desire to secure by Letters Patent: ].{ln a flushing valve, the combination of a supply pipe, a valve mounted in said supply pipe and adapted to he closed by the pressure ol the water in said supply pipe, a dash polmounted at the side of said supply pipe. and provided with an opening connecting said SIIIDPlY'PlIJG below said valve with the upper part. of said dash pot and means for securing the cooperative action of said valve and the piston of said dash pot, substantially as shown and described.
